Magic Is All I Need

It's been 10 years ever since that incident..
Two siblings, Stephen and Annabelle Addison, lost their parents due to an enemy who happened to set their house ablaze and try to kidnap them.
Since they were fortunate, the two of them escaped the house. But, the enemy is still on the loose.
Years later, Stephen and Annabelle found their own place which they have been living in with the help of their family's friends.
In order to keep up with the expenses, they both have their own part-time job.
In the mean time, they attend a magic academy to make their magic and combat skills more sharp so in the future they can kill the enemy who killed their parents together, and stop the man once and for all.
